15 steps

Removing the enclosure screws

Depending on when your iPhone was manufactured, you’ll need either a Phillips screwdriver or a pentalobe screwdriver to open your phone.

Depending on when your iPhone was manufactured, you’ll need either a Phillips screwdriver or a pentalobe screwdriver to open your phone. They are located to the right and left of the dock connector. Put the screws in the same compartment of your organizer tray.2 x 3.6 mm pentalobe/Phillips screws

Removing the back cover

Use your thumbs or the palm of your hand to push the back cover of your iPhone about 4 mm away from the bottom of the phone where the dock connector is (see figure 1).

Then you can lift the back cover at the end that’s sticking out past the phone (see figure 2).

Disconnecting the battery connector

If your iPhone’s still on, turn it off now by holding down the standby button for about five seconds and following the prompt on the display.

Remove the screw on the battery connector using a Phillips screwdriver (see figure 1). Put the screw in a separate compartment of your organizer tray.1 x 2.6 mm Phillips screwThe battery contact point on the logic board could come off. If the contact point breaks off but the soldering points are still intact, you can solder the contact point back on.

Now carefully lift off the battery connector by inserting the pointed ESD spudger slightly below the silver cover plate (see figure 2). If you don’t have a spudger, you can also try using your fingernail.

For the rest of the repair, you can also use the metal laboratory spatula instead of the spudger. This may make some steps easier for you. However, we explicitly recommend using the ESD spudger produced specifically for precision electronics.

Removing the battery

The antenna cover is under the battery connector. NRemove the cover and put it in the same compartment of your organizer tray as the Phillips screw you removed before. (See figure 1).

Now remove the battery. It’s sometimes glued firmly in place. Insert the flat end of the spudger into the space (about 1 cm to the left of the volume down button) between the battery and the outer frame, and slowly lift the battery (see figure 2). If the battery’s really stuck on, use other leverage points to the right and left of the original spot to pry it off. If you still can’t detach the battery, you can use a heat gun to warm it slightly from the outside and soften the glue.

Now you can also disconnect the antenna connector by carefully pulling it off the plug head using the spudger (see figure 3).

Plastic tab

Fold the plastic tab with the warning over and press it firmly onto the lower adhesive strip. This way, it won’t get in the way during your repair.

Installing the speaker

The speaker’s clips have to be against the speaker behind the higher level of the middle cover (see figure 2). This is easiest if you only slightly screw in the speaker at first so it can still move around a little.

Once the clips are fitted properly, you can tighten the screw.

Attaching the dock connector cable

Connect the dock connection cable again and put the black/silver cover on it.
